BellSouth Corp. has extended its relationship with Alcatel to provide next-generation DSLAM (digital-subscriber-line access-multiplexer) technology that would pave the way for the regional Bell operating company to offer Internet-protocol-video service over DSL lines.
BellSouth said Alcatel will be the "preferred" supplier of IP DSLAMs over the next three years as the telco expands its network.
Alcatel will supply its “7330” DSLAM, while RedBack Networks Inc. will provide its “SmartEdge 800 Service Gateway.” The platform will allow BellSouth to roll out ADSL2+ technology, capable of delivering 24 megabits per second to the home over a pair of bonded copper lines.
The telco is testing IP video in its labs, and it would use the 24-mbps path to deliver a mix of voice, video and data services.
"We believe it is possible to provide speeds fast enough to make triple-play services over IP a reality using a mosaic approach of fiber and next-generation DSL," BellSouth chief technology officer Bill Smith said in a prepared statement.
